DISCUSSION: The existing Live Oak Sewer Lift Station is located at 731 Verna Trail , which is north of White Settlement Road and west of Loop 820 West. In 1989, the Live Oak Lift Station was constructed to provide sewer service to the Silver Ridge subdivision . Currently, wastewater drains from the Silver Ridge and Live Oak Creek subdivisions into a gravity sewer line connected to the Live Oak Lift Station . Wastewater is then pumped from the Live Oak Lift Station approximately a mile to a gravity sewer line located near Silver Creek Road and Loop 820 West. The existing submersible pumps in the Live Oak Lift Station are twenty years old and require replacement. Over the Memorial Day weekend , both pumps failed, resulting in an emergency response using bypass pumps and wastewater trucking . Following the emergency, the Water Department expedited the design of the rehabilitation of the Live Oak Lift Station. The rehabilitation work will include a new emergency bypass manhole and pump , two new submersible pumps to be installed in the existing wetwell , new electrical hardware, and new piping, valves and fittings in the existing wetwell and valve vault. The project was advertised for bid in the Fort Worth Star Telegram on August 5 , 2010 and August 12 , 2010.

Groundwater was observed at a depth of about 27 feet during drilling in the boring. At completion, a groundwater level of about 15 feet was measured. These observations represent only current groundwater conditions , and may not be indicative of other times or at other locations . Groundwater conditions can change with varying seasonal conditions , landscape irrigation , and other factors . 2 Geotechnical Engineering Report Live Oak Lift Station aFort Worth , Texas July 29 , 2010 • Terracon Project No . 95105048 llerracan 4.0 RECOMMENDATIONS FOR DESIGN AND CONSTRUCTION 4.1 Engineering Recommendations Excavation for the structure will extend through clay , sandy clay , sand and gravel and clayey sand soils , which must be sloped or braced in the interest of safety . Applicable OSHA standards would apply . Groundwater will be encountered during the excavations . Groundwater was encountered at a depth of about 15 feet in the boring . Dewatering will be necessary during excavations. It is planned to support the bypass manhole with a cast in place reinforced conc rete mat foundation. The foundation will be situated at an elevation of about 605 feet , which is estimated to be about 30 feet below the existing grade . The foundation will be situated in the sandy clays , sand and gravel or clayey sand soils . The footing should exert a maximum bearing pressure of 2 ,500 pounds per square foot (PSF). Settlements for the footing are expected to be less than 1 inch in these soils. 4.2 Below Grade Walls Recommended lateral earth pressures expressed as equivalent fluid pressures are presented below in Table 2 for rigid walls for undrained conditions . Rigid walls are not anticipated to deflect sufficiently to mobilize active earth pressures . TABLE 2-EQUIVALENT FLUID PRESSURES Bacl<fill Material · ,. On-sit e clay and sandy clay soils On-site sands and clayey sands At.:Res.t ,(Rigid) 110 pcf 95 pcf The lateral earth pressure values do not include surcharge loads due to overburden , traffic , equipment , etc . Surcharge loads should be considered if they apply at the surface above the wall within areas defined by an angle of 45 degrees from the base of the wall. A lateral pressure coefficient of 0.5 is recommended for uniformly distributed surcharge loads . Backfill materials should be placed in loose lifts , less than 9 inches thick, and uniform ly compacted to a minimum density of 95 percent of ASTM D 698. Moisture content during placement of cohesive backfill should be within O to +4 percentage points of the optimum moisture content as measured in test method ASTM D 698. Care should be taken that backfill is not over compacted , which could increase the lateral pressures on the walls. 3 Geotechnical Engineering Report Live Oak Lift Sta.tion aFort Worth , Texas July 29 , 2010 • Terracon Project No. 95105048 lrerracan Settlement of the wall backfill should be anticipated . Piping and conduits through the fill should be designed for potential soil loading due to fill settlement. Flatwork, sidewalks and pavements over fills may also settle. Backfill compacted to the density recommended above is anticipated to settle on the order of one to two percent of the fill thickness. 4.3 Drainage All grades must be adjusted to provide positive drainage away from the structure. Open ground should preferably be sloped at a minimum of 5 percent grade for at least 1 O feet beyond the perimeter of the structures . Where paving or flatwork abuts the structures, care should be taken that the joints are properly sealed and maintained to prevent the infiltration of surface water. 5.0 GENERAL COMMENTS Terracon should be retained to review the final design plans and specifications so comments can be made regarding interpretation and implementation of our geotechnical recommendations in the design and specifications . Terracon also should be retained to provide observation and testing services during grading, excavation , foundation construction and other earth-related construction phases of the project. The analysis and recommendations presented in this report are based upon the data obtained from the borings performed at the indicated locations and from other information discussed in this report. This report does not reflect variations that may occur between borings , across the site, or due to the modifying effects of weather. The nature and extent of such variations may not become evident until during or after construction. If variations appear, we should be immediately notified so that further evaluation and supplemental recommendations can be provided. The scope of services for this project does not include either specifically or by implication any environmental or biological (e.g., mold , fungi , bacteria) assessment of the site or identification or prevention of pollutants, hazardous materials or conditions. If the owner is concerned about the potential for such contamination or pollution, other studies should be undertaken . This report has been prepared for the exclusive use of our client for specific application to the project discussed and has been prepared in accordance with generally accepted geotechnical engineering practices. No warranties , either express or implied, are intended or made. Site safety, excavation support, and dewatering requirements are the responsibility of others. In the event that changes in the nature, design, or location of the project as outlined in this report are planned, the conclusions and recommendations contained in this report shall not be considered valid unless Terracon reviews the changes and either verifies or modifies the conclusions of this report in writing . 4 APPENDIX A FIELD EXPLORATION Dofe, 07/2,J/iO O:\HE;JC\fort, wor~h\26id\951.(),5048,dwg, L.r,yoµt: Layovt1 Current Lqyer: 0 t::ff:t}fla°si:~1/ay F~OMORiGiNAt..REPdRf. ~Oll;: BORING ~OOATJC>NS Ii.RE 1f"P,Rb~,MATE, }t,.'\~ * l'illl<'tMl?l ¢cpll~,.,_. 95105048 ,------1 i I i I I PRQPQSEQ I I W_ET WELL. .

The bor ing was located in the field by a representat ive of Terracon and the City of Fort Worth using a site plan provided by the client. The boring location should be considered approximate . Truck-mounted drilling equipment was used t o advance the boring . Samples of the soils encountered in the boring were obtained using thin -walled tube and split-barrel sampling procedures . The samples were tagged for identification , sealed to reduce moisture loss , and taken to the laboratory for further examination, testi ng , and classification . A log of the boring is presented on Exhibit A-2 in Appendix A. General notes for log terms and symbols are presented on Exhibit C-1 . A field log of the boring was prepared by the drill crew . The log included visual classifications of the materials encountered as well as interpretat ion of the subsurface conditions between samples . The boring log included with this report represents the engineer's interpretation of the field log and include modifications based on laboratory evaluation of the samples . Exhibit A-3 Geotechnical Engineering Report Live Oak Lift Station aFort Worth , Texas July 29 , 2010 • Terracon Project No . 95 105048 Laboratory Testing lrerracan The drilling log and samples were rev iewed by a geotechnical engineer who selected samples for testing . Tests were performed by technicians working under the direction of the engineer. A brief description of the tests performed follows . Liquid Lim it , Plastic Limit and percent pass ing the m inus #200 mesh sieve tests were performed on selected soil samples . These tests were used in conjunction with moisture content measurements to aid in classifying the soils in accordance with the Unified Soil Class ification System (USCS). The USCS is summarized on Exh ibit C-2 in Appendix C . These tests were also used for evaluating soil volume change potential. Hand penetrometer and unconfined compression tests were perfo r med on samples of the cohesive soils to evaluate the consistency and strength of these materials . The results of the laboratory tests are presented on the Log of Boring in Appendix A.

Groundwater levels at other t imes and other locations across the s ite could vary. In pervious soils , the indicated levels may reflect the location of groundwater. In low permeability soils , the accurate determination of groundwater levels may not be possible with only short-term observations. DESCRIPTIVE SOIL CLASSIFICATION: Soil classification is based on the Unified Classification System . Coarse Grained Soils have more than 50 % of their dry weight re tained on a #200 sieve; their principal descriptors are : boulders , cobbles , gravel or sand . Fine Gra ined Soils have less than 50 % of their dry we ight retained on a #200 sieve ; they are principally described as c lays if they are plastic, and silts if they are slightly plastic or non-plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain s ize . In addition to gradation , coarse-grained soils are defined on the basis of their in-place relative density and fine-grained soils on the basis of their consistency.
